Spook Country (Blue Ant #2) by William Gibson

Tito is in his early twenties. Born in Cuba, he speaks fluent Russian, lives in one room in a NoLita warehouse, and does delicate jobs involving information transfer.

Hollis Henry is an investigative journalist, on assignment from a magazine called Node. Node doesn't exist yet, which is fine; she's used to that.

But it seems to be actively blocking the kind of buzz that magazines normally cultivate before they start up. Really actively blocking it. It's odd, even a little scary, if Hollis lets herself think about it much. Which she doesn't; she can't afford to.
